Product Options Performance and Packaging Options Magna-Power Electronics programmable DC power supplies are designed to be as versatile and expandable as possible. A variety of options are available allowing the product to deviate from its standard specifications. This section provides an overview of the available performance and packaging options and products supported. Cabinet and Integration High Isolation Output CAB1, CAB2, CAB3, CAB4, CAB3x2, CAB4x2 SL Series, XR Series, TS Series +ISO TS Series, MS Series, MT Series Cabinet and integration services are offered for the rackmount programmable DC power supply products. Cabinets are supplied with fans rated to installed products. Key features of the cabinet and integration option are as follows: Hoffman cabinet frames Casters installed, including (2) locking casters Special circuitry for product integration with cabinet fans Installation and testing as a complete system Cabinet and Integration Specifications Cabinet Name Dimensions (H x W x D ) Rack Units CAB1 32 x 24 x 31.5 12U CAB2 51.5" x 24" x 31.5" 24U CAB3 67 x 24 x 31.5 30U CAB4 75 x 24 x 31.5 36U CAB3x2 67 x 48 x 31.5 60U CAB4x2 75 x 48 x 31.5 72U High Slew Rate Output Certain applications require floating the output voltage to values beyond the power supply s standard isolation rating. Magna-Power Electronics High Isolation Output option (+ISO) enables any TS Series, MS Series, or MT Series model with a peak output voltage rating of 250 Vdc through 1000 Vdc to be rated for a higher voltage output isolation. Improved isolation is achieved by a novel output stage with improved controller isolation. In addition to being able to float the power supply to a higher output voltage, this option also enables lower voltage units to connected series up to the higher isolation rating. The table below provides the output isolation rating for all available configurations, where Vo is the unit s rated maximum output voltage.

Rapid voltage transitions require internal electronics to supply the energy to charge and discharge output capacitors. Peak currents internal to the power supply define slew rate; utilizing less capacitance enables voltage transitions in shorter time periods. Additionally, less capacitance reduces requirements for discharge demands during open circuit conditions. The standard output stage Magna-Power Electronics power supplies has been designed to provide the lowest possible output ripple voltage within the constraints of available components, size, and cost. Part of the output stage consists of a bank of aluminum electrolytic capacitors which has the desired electrical properties to provide this function. These components require bleed resistors to discharge any voltage when the power supply has no load and is disabled. While the presence of Slew Rate Specifications Slew rate standard Voltage 100 ms 4 ms Current 100 ms 8 ms Slew rate with +HS option these components and the resulting performance are normally industry accepted, there are applications where lower output capacitance is extremely desirable and higher ripple voltage is acceptable. To meet this need, a high-slew rate option is available which has an output stage consisting of low capacitance film and aluminum electrolytic capacitors. Applications for the high-slew rate option include battery charging, photovoltaic emulation, power waveform generation, and medium speed power pulsing. These applications all benefit from higher bandwidth and in many cases, can tolerate the increased ripple voltage of this option. 30

UID47: Universal Interface Device UID47 Magna-Power Electronics UID47 is a general purpose device for connection to Magna-Power Electronics power supplies. The device contains the necessary circuitry for configuring power supplies for master/slave parallel or series operation. Master/slave parallel operation allows two or more power supplies to equally share output current when connected together. Master/slave series operation allows two or more power supplies to equally share output voltage when connected together. In either operation mode, the master unit will command the slave units to the proper voltage and current. Each unit will display its own individual voltage and current. Installation requires setting jumpers, placing included 37-conductor cables between the UID47 and power supplies, and wiring the power supply outputs in either parallel or series. The UID47 can be used as an interface for connecting control and monitoring lines to external circuitry. It also contains an area on the printed circuit board for interconnecting wires and placing components for specific user applications. Key features of the UID47 option are as follows: Compatible with all Magna-Power Electronics power supplies Interface for series and parallel master/slave operation User configurable screw terminal connector Pad area for custom circuitry (2) 6-foot 37-pin cables included Water Cooling +WC TS Series, MS Series Water cooling is available for Magna-Power Electronics TS Series and MS Series power supplies typically for use in corrosive environments, such as electroplating applications or in densely packaged system cabinets, where heat removal by air cooling presents a problem. Water cooling is accomplished with chill plates and an integrated central heat exchanger. The chill plates provides a thermal conduction path for heat sensitive components and the central heat exchanger removes heat from air internal to the enclosure. Water cooled TS Series models have enclosures without vent holes and are basically sealed the unit from the environment. An internal solenoid valve enables water flow when the chill plate reaches 60 degrees celcius. Operation of the solenoid prevents internal condensation. Water Cooling Specifications 5 kw - 15 kw Models 20 kw to 30 kw Models 45 kw to 75 kw Models Inlet Coolant Temperature 25 C 25 C max 25 C max Flow Rate (Min) 1.5 GPM 3.0 GPM 4.5 GPM Pressure (Max) 80 psi 80 psi 80 psi Inlet/Outlet Pipe Size 1/4 NPT male 1/2 NPT male 1/2 NPT male Each 15 kw module has a 1/4 NPT female inlet and outlet for water flow. For models greater than 15 kw, external plumbing interconnects power supply modules. A minimum of 2.50 is recommended behind the enclosure for this hardware and user connections. For systems requiring more than one power supply, plumbing connections must be paralleled; that is, water should not flow from one power supply into another. www.magna-power.com 31

Product Options Communication Interface Options All Magna-Power Electronics programmable DC power supplies come standard with RS232 serial interface and 37-pin isolated analog/digital I/O. Additional available interface options are available, as detailed in this section. IEEE-488 GPIB USB Edgeport (Adapter) +GPIB USB The IEEE-488 interface, sometimes called the General Purpose Interface Bus (GPIB), is a general purpose digital interface system that can be used to transfer data between two or more devices. It is particularly well-uited for interconnecting computers and instruments. Some of its key features are: Up to 15 devices may be connected to one bus Total bus length may be up to 20 m and the distance between devices may be up to 2 m Communication is digital (as opposed to analog) and messages are sent one byte (8 bits) at a time Message transactions are hardware handshaked Data rates may be up to 1 Mbyte/sec Edgeport USB-to-serial converters offer instant I/O expansion for peripheral device connectivity. An out-of-the-box (external) alternative to PCI cards, Edgeport makes it easy to add serial port to a PC, server or thin client in minutes without opening the chassis, reconfiguring or rebooting the system. The USB Edgeport device plugs directly into the back of the power supply, creating a seamless USB interface. Featurerich design, reliability and unmatched operating system support make Edgeport USB-to-serial converters ideal for mission-critical enterprise applications. USB cable included along with associated drivers on the Magna-Power Electronics software CD. LXI TCP/IP Ethernet +LXI Certified to the LXI Standard (Class C), the TCP/IP Ethernet option includes an embedded web-server, allowing web browser power supply control and monitoring from virtually anywhere. LXI is an instrumentation platform based on industry standard Ethernet technology designed to provide modularity, flexibility, and performance to small- and medium-sized systems. LXI s advantages are exemplified in its compact, flexible package providing high-speed I/O and reliable measurements. The Magna-Power Electronics LXI TCP/IP Ethernet option includes an embedded web-server, allowing web browser power supply control and monitoring from virtually anywhere. RS-485 (Adapter) RS485 The RS-485 allows non-addressable, dumb RS-232 devices to be connected on an addressable RS-485 network. The master node controls all communications to connected devices. By distributing the switching intelligence along the RS-485 network, wiring cost savings are substantial compared to a single switched star configuration. Devices can either be polled by the master node or request access to the bus through a RS-232 handshake line. This provides a versatile system for interconnecting devices that are designed for point to point communications. Because the units communicate using standard RS-485 signals, RS-232 devices can form their own network or be added to an existing system. Up to 32 nodes at up to 4000 feet can be on one bus without a repeater, and the 485DSS s addressing scheme allows up to 256 units on a single network with repeaters. 32

Magna-Power Electronics Programmable DC Power Supplies Technology and Feature Overview Innovative and Scalable Magna-Power Electronics programmable DC power supplies combine the best of DC power processing with microprocessor embedded control. A combination of high and medium frequency power processing technologies improves response, shrinks package size, and reduces cost. All Magna-Power Electronics DC power supplies are current-fed and are more tolerant to abusive loads than conventional switching power supplies. This technology allows the power supply to operate under short-circuit conditions, open-circuit conditions and everything in between. The programmable DC power supplies offer both master/ slave parallel and series operation. This enables two or more power supplies to be placed in parallel for increased output current or in series for increased output voltage, within the unit s isolation limits. With master/slave operation, power supplies operate at near equal voltage and current. The process of master/slaving power supplies is plug & play with the use of Magna-Power Electronics UID47 option, which can be added at any time. All supplies can operate as a voltage source or current source depending on the control settings and load conditions. If the power supply is operating as a voltage source and the load increases to a point beyond the current command setting, the power supply automatically crosses over to current mode control and operates as a current source at that setting. Designed for Safety Magna-Power Electronics programmable DC power supplies have extensive diagnostic functions all of which, when activated, take command to shut down the system. Diagnostic functions include phase loss, excessive thermal conditions, over voltage trip, over current trip, fuse clearing, and program line. Program line monitors externally applied analog set point signals to insure they are within the specified range. Upon a diagnostic fault condition, main power is disconnected and the diagnostic condition is latched into memory. Pressing the clear key clears the memory. All diagnostic functions can be monitored through the rear connector and software. Furthermore, control functions can also be set through the rear connector to allow simultaneous control of one or more power supplies. The power supplies have three levels of over voltage/current protection: shutdown of controlling insulated gate bipolar transistors (IGBTs), disconnect of main power and input fuses. After an over voltage/current trip condition, the supply fault must be cleared. Isolated External I/O for Automation Using the rear isolated 37-pin I/O connector, the programmable power supplies can be completely controlled and monitored using external signals. The voltage, current, over voltage and over current set points are set by applying a 0-10V analog signal. Each diagnostic condition is given a designated pin, which reads +5V when high. Reference +5V and +10V signals are provided, eliminating the need for external voltage signals and allowing the use of dry contacts. Also, the power supply features a normally closed external interlock, which when enabled, allows the power supply to be tied in with other emergency stop equipment. All these pins are isolated to earth-ground as standard no additional isolation equipment or options necessary. Fully Programmable The Magna-Power Electronics programmable DC power supplies can be programmed and monitored using three possible sources: Stepless front panel programming knobs External analog/digital signals Computer interface through included software, Lab- VIEW, or other programming environemnt The power supply can be programmed to have its control functions accessible from the front panel, rear connector, RS232 (standard), LXI TCP/IP Ethernet (+LXI), IEEE 488 GPIB (+GPIB), USB Edgeport (+USB), or RS485DSS (+RS485) communications. The included IVI driver enables programming in a variety of software environments, including: Visual C++, Visual C#, Visual Basic.NET, Visual Basic 6.0, LabVIEW, LabWindows/CVI, MATLAB, Measure Foundry, and Agilent VEE Pro. Basic programming requirements are satisfied by the instrument s supported Standard Commands for Programmable Instruments (SCPI). Sensing can be established at the output terminal of the power supply or through a rear remote sense terminals for sensing at the load. Even calibration has been simplified with front panel access to digital calibration potentiometers. Attention to Power Quality All Magna-Power Electronics power supplies contain circuitry to work harmoniously with other power equipment. Step-start contactors are used to keep inrush current below full scale operating current. Filter components lower current harmonic content emanating from the power supply and increase power factor to levels beyond 90%. Every power supply is tested at 90% to 125% nominal line to insure satisfactory operation even under the worst line voltage conditions. Electronic Output Stage The novel electronic output stage (SL/XR/TS/MS Series) utilizes near constant power loading under all conditions via an electronic bleed resistance. This electronic bleeder means stability under all operating conditions and faster fall times, without affecting the overall system efficiency. 4
